ABSTRACT
To date, the clinical pattern and electrocardiographic diagnosis of only one variant of coronary heart disease (CHD) with unchanged coronarogram, Prinzmetal's angina, have been worked out, while the diagnosis of other variants remains undeveloped. Clinical symptoms and possibilities of CHD diagnosis in the presence of intact coronary arteries have been evaluated in 67 coronary patients, the coronarograms being normal in 46 of those. The diagnosis of CHD was verified by means of various instrumental methods, including electrocardiographic tests and myocardial metabolic studies in conditions of frequent atrial stimulations. The results were computerized, using a specifically designed programme. Sets of signs identifying coronary patients with intact coronary arteries at questioning and noninvasive investigation are presented.

A standard questionnaire, capable of describing chest pain sensations, has been offered for patients with coronary disease and neurocirculatory dystonia, and its diagnostic value is assessed. The questionnaire comprises five sections, each corresponding to a certain type of pain. A diagnostic statement is made after each section. The questionnaire can be analysed by a physician on the basis of individual clinical experience, or computer-processed. It possesses high sensitivity and specificity in detecting typical and atypical angina and cardialgia of different types. The questionnaire can identify a category of patients with chest pains, who require instrumental diagnostic investigation to specify their origin.

A program of automated calculation of an individual diet for patients with diabetes mellitus and obesity has been worked out for the Elektronika HMC-80 PC. During a 15-20 min. interactive dialogue with the PC the caloric value and balance of a diet of 160 food items are assessed. Indices like sex, age, height, body mass, physical activity and diet are taken into account in dietary calculation. The testing of the program under clinical conditions has shown its multifunctional nature: it permits the detection of disturbed quantitative (caloric value) and qualitative (the ratio of proteins, fats and carbohydrates) indices of a diet, errors of an inpatient dietetic service and helps to form habits of nutritional culture in patients and medical staff.
